PROCESS FR' GLEANING TUBULAR BODIES.

Application filed April 29, 1912.

To all wh-0m t may concern:

Be it known that I, HERMANN EBERHARDT, a subject of the German Emperor, residing at Breslau, Germany, have invented a certain new and useful Process for Cleaning Tubular Bodies, of which the following is a specification. Y

Intestines have been rendered lelastic for the purpose of cleaning by drawing them over an eXpansible` body, the distension of which was brought about by means of liquid or air pressure. The impurities adhering to the outside of the intestines, more particularly pieces of fat and sinew, were scraped off, by quickly rotating brushes or knives. The scraping tools are, however, quickly covered with impurities, so that the work has to be frequently stopped for cleaning purposes. This drawback is obviated according to this invention by exposing the elastic intestines to the action of quickly rotating combs. The elastic state of the intestines is as essential as the use of combs, the

cleaning of intestines, which are not made elastic, by quickly rotating combs, being just as unsatisfactory as cleaning elastic intestines by rotating brushes or knives. When the intestines are not made elastic there are formed creases which are inaccessible to cleaning and the wall of the material is frequently injured by the cleaning tools even when rotating combs are used; moreover the brushes are yielding and therefore yield to the impurities, rather than tear them off,

while knives do not remove them completely j but merely press the impurities flat against the wall of the intestine.- If, however, the elastic intestine is cleaned by means of Vquickly rotating combs, first of all a complete lseparation of the impurities will be effected, as each of the many teeth not yielding in the direction of rotation of the comb .engages with the impurities and tears them off, and moreover owing to the elasticity of the intestine its walls are not injured. The intestins is ,further accessible cn all. sides to Specification ofLetters Patent.

" connected to an electric motor 4 making about 170() revolutions per minute. The cylinder is mounted at the top and at the bottom on pins 11 or 11', in bearings 8 or 14 of a frame 15, 5, the bottom plate 5 of i which` provided with handles 6, is used for securing the motor 4. For connecting the combs 3 to the cylinder 2, the latter is provided with projecting pairs of ledges l0 which form with each other a groove in which a comb is inserted; the said groove being' covered at the end by the collar or flange 9 of the cylinder.

On the pin 11 of the cylinder is placed the covering plate 12 which rests on the top of the combs 3. By tightening the screw 13, the combs 3 are fixed firmly between the covering plate 12 and the flange 9 of the cylinder. ln the central plane of the cylinder,

plates 16 project from the stand 15, where What I claim as my invention and desire' to secure by Letters Patent isz- The process of cleaning intestines whichv consists in elasticallyf distending the intestines and combing the so distended portions at a high speed.

In testimony whereof I have signed myv is Y name to this Speoiication in the presence of VI5 Copies of this patent may bepbtaned for five cents each, by addressing` the Commissioner of Patents, WashingtomrD. C.
